UVATERV (abbreviation for the Road and rail design company) was a building design company in the ancient regime and the photoarchive was gifted to Fortepan. A few days before delivering the collection the house caught fire. Firefighters water soaked the whole negative collection, and a group of volunteers worked to rescue the surviving material. The photographers of each picture have not been identified, probably they was employed by UVATERV.
